HEIDI FLEISS DUMPS HER 'VIAGRA-TAKING PIG'

Former Hollywood Madam Heidi Fleiss has dumped live-in boyfriend Tom Sizemore for the second and last time, calling him a "Viagra-taking pig."

"Tom may be a hero to fans of the new CBS show 'Robbery Homicide Division,' but to Heidi he is the ultimate scumbag," an insider declared.

Friends say the romance is over for good -- and that Heidi went so far as to get her lawyer to send Tom a letter warning him to stay away from her!

The ENQUIRER reported in June that Heidi walked out on her yearlong relationship with Tom after we ran a story detailing his out-of-town sexcapades with prostitutes.

The couple reconciled, but "not long after Heidi moved back in with Tom, she started getting calls from hookers she knew from her earlier days, warning her that Tom was using prostitutes," another source disclosed.

Heidi told a friend, "Hookers are calling me and telling me he stiffed them out of money. Another woman told me the sexual favors Tom wanted were gross. He was doing Viagra all the time. The guy is a Viagra-taking pig."

Several weeks ago, things got really ugly between the couple.

"Tom threatened to put Heidi back in prison if she attempted to leave him," said the source.

"Heidi is on parole and can be sent to prison for failing a drug test. A close friend said Tom threatened to put drugs in her food and then tell her parole officer. Afraid of what he might do, Heidi confided her fears to her parole officer.

"She now says, 'The thought of me ever being with that man again makes me physically ill!'"
